I am not sure if this is the sandbox effect that I am seeing.
I recently modified my dynamic site (initially launched in sep 2003)
to make it search engine friendly with mod_rewrite. Approx after 10 days googlebot crawled close to 100 pages and the same got indexed a couple of days thereafter.
Earlier i.e. before I did mod_rewrite, there were only a few pages that were indexed. Also the PR was and still is 4.
The other differece that I have noted is that earlier googlebot visited only the homepage daily, now it visits 6 pages daily.
For a few keywords, not too competitive I turn out okay on the first or the second page. But for the keyphrases for which I would really like to rank, I am nowhere. When I add -adsdas (many times to cross the 10 word limit) I turn up on the first page.
Could this be the 'sandbox effect' since the number of links to the site increased suddenly due to simultaneuos indexing of 100 pages (the footer containing all the main links)?
Do I have any hope of being on the first page or could the -addsda characters be switching off other relevant filters?
Another observation, is that after the indexing of the pages, the home page title for which I ranked number 1, I moved down to number 4. But with the -saddsa characters I am number one again. There are around 450,000 total competing pages for the title.
Your help in analysing the results would be appreciated.
